Long-Term Healing From Infidelity and Affairs


Maybe it was a text that lit up their phone while they were in the shower, maybe it was a credit card statement for a hotel you never stayed in, maybe your partner finally admitted what you already suspected. However it happened, you’re now living in the aftermath of partner betrayal and the trauma it causes.

You’re still going to work, still picking up the kids from school, still showing up to meetings and making dinner and doing all the things you’re supposed to do. But your nervous system is in constant alarm mode. You’re checking their location obsessively, you’re replaying the discovery over and over, you’re having physical reactions when you see their name on your phone. The intrusive images of what they did interrupt your work calls, your conversations with friends, and your attempts to fall or stay asleep.

If you’re looking for a Portland therapist who specializes in partner betrayal trauma (not general anxiety, not couples counseling, but the specific trauma that comes from infidelity), I can help. I specialize in partner betrayal and infidelity, including sexual affairs, emotional affairs, and pornography betrayal. I use Accelerated Resolution Therapy (ART) to resolve the trauma response in 1-5 sessions rather than months of weekly therapy.

About Partner Betrayal Trauma

Partner betrayal trauma (sometimes called post-infidelity stress disorder) creates symptoms that mirror PTSD: thoughts and images you can’t control, being on edge about your partner’s whereabouts and text messages, nightmares, difficulty concentrating, and physical reactions when triggered. You might find yourself checking their social media, reading old texts, driving by places they might be, or interrogating them about every detail of their day.

The shame spiral runs constantly. “Why wasn't I enough?” “How did I miss the signs?” “What’s wrong with me that this happened?” You’re not just grieving the betrayal, you’re questioning your own worth, your own judgment, your own reality. The person who was supposed to be your safe place turned out to be the danger, and now you don’t know what or who you can trust, including yourself.

You replay the happy memories and wonder if any of it was real. The vacation where they seemed so present, the anniversary dinner where they said they loved you, the morning they kissed you goodbye and then went to meet someone else. Your entire history together feels contaminated, and you can’t tell which parts were genuine.

Your brain has become a full-time detective. You’re analyzing their word choices, monitoring their location, checking timestamps on messages, noticing when they tilt their phone away from you. Every late night at work, every text from an unknown number, every moment of distraction becomes evidence to be examined.

The images won’t stop. Not just memories of what you discovered, but scenes your brain constructed from the details you learned. You picture them together in the hotel room, in the car, in places you’ve never even seen. These images intrude while you’re working, while you’re driving, while you’re sitting across from them at the dinner table. You didn’t choose to see these things, but now you can’t unsee them.

Here’s why this is happening: your brain experienced something that felt life-threatening to your sense of safety and identity, and now it’s still in protection mode, constantly scanning for the next threat. The problem is that your brain can’t distinguish between an actual current threat and the memory of what happened, so it keeps responding to the past as if it’s still happening right now.


Accelerated Resolution Therapy Works Quickly for Betrayal Trauma


Most therapists who work with infidelity use talk therapy approaches that process the experience gradually over months. You tell the story, you talk about the emotions, you work through trust issues, you learn coping skills. This takes time, usually six months to a year of weekly sessions.

ART works differently. Instead of processing the trauma through repeated retelling, ART uses eye movements and visualization to change how the memory is stored in your brain. The facts stay, but the emotional charge, the physical response, the intrusive quality, those change. Most people complete treatment in 1-5 sessions.


How ART differs from EMDR for betrayal trauma:

You may have heard of EMDR (Eye Movement Desensitization and Reprocessing).

ART uses similar eye movements but the two modalities have key differences. EMDR lets your mind free-associate wherever it goes, revisiting the same memory across multiple sessions until it processes. ART is more directive, meaning I guide you through specific steps to change the image or memory, often in just a single session. In other words, during ART, you’re actively changing what you see rather than passively processing.

Most people find ART more tolerable than EMDR because:

  1. You don’t have to verbally process the images or memories

  2. You have control over the image replacement

  3. Resolution happens faster


Life Changes After Treatment for Partner Betrayal Trauma


Through our work together, you’ll stop surviving and start living. Not managing trauma and anxiety, not coping with the daily panic and anxiety, not white-knuckling through each day. Actually living with spontaneity, joy, and the freedom to choose your life instead of the aftermath of betrayal choosing it for you.


What changes after our work together…


  • The unwelcome thoughts about the infidelity stop. When you think about what happened, you can recall the facts without your body flooding with adrenaline, without the images playing like a movie you can’t turn off, without losing the next two hours to rumination. You get your mind back.

  • Your partner’s phone buzzes or they grab their laptop and your stomach doesn’t drop. They mention drinks with coworkers and you say “have fun” and mean it. The constant on-edge feeling that has been running in the background finally shuts off.

  • You’re present at work. You're contributing in meetings, tackling projects you’ve been avoiding, having conversations without mentally drifting somewhere else. The mental bandwidth that was consumed by obsessive thoughts is now available for actual thinking, problem-solving, and creating.

  • You make major decisions from clarity. Whether to stay, whether to leave, whether to try reconciliation, how to handle finances, what to tell the kids: you think through your options, weigh the tradeoffs, and choose a direction because it’s the right choice for you, not because panic pushed you into it.

  • You have the necessary and difficult conversations. You ask the hard questions, set the boundaries, negotiate terms for whatever comes next. The conversation ends and you move forward instead of circling back to the same fight for the seventeenth time.

  • You’re intimate again. You reach for your partner (or a future partner) because you want to, not because you're trying to prove something. You're in your body during sex, connected to what's actually happening instead of somewhere else.

  • You move through Portland like it’s just a city. You drive past the restaurant, the hotel, or the strip clubs, and you’re thinking about where you’re going, not where they went, or who they met up with. You make plans based on what you want to do, not taking the long way to avoid a triggering place.

  • You show up for the people who matter. You’re playing with your kids instead of going through the motions. You’re enjoying dinner with friends instead of acting like everything is normal. You’re enjoying your life instead of just managing the damage.

About Allyson Clemmons, LICSW
Portland Partner Betrayal Trauma Therapist

My specialization in partner betrayal trauma emerged from years of treating affairs as a couples therapist. While couples work was essential for the relationship, I noticed betrayed partners also needed specialized individual therapy that wasn’t available. They would only find generic trauma treatment that kept them talking in circles for months, while their nervous systems remained hijacked by the betrayal.

I noticed that partner betrayal creates a specific type of trauma that requires targeted treatment. The neurological impact is profound, and it doesn’t resolve through insight or understanding alone.

Now I exclusively use Accelerated Resolution Therapy to help people move from obsessive investigating and constant triggering to genuine peace in just 1-5 sessions. You don’t need to manage partner betrayal trauma indefinitely. You can actually resolve it.
